The invention 'relates to measuring pumps for dispensing gasoline and other oilsy and morev especially to apparatusin Which thev yIt has been found'that in the 17Voperationgofv thesev pumps it is usuallyinotpossible' tofrely' on perfecttightness' of the .valvestherfeof 'or' ofthe pipes connected therewith;` and consequently a correct delivery of the gasoline n or oil cannot be ,assuredz afterfthepumplias stood unused `for a numberof hours, as for exampleover night.v 'Thus .the first customer of the morning may4 receive short measure although a complete stroke of Y the pump is made and thelfull quantity supposed to.' badelivered is registered on the, meter associated therewith.' y Y Y "It is the object of the present invent/ion to equip a defined-stroke piston type of measuringpump With means vvhichwill provide for accurate discharge of selected'quantities f of gasoline orother liquid;v and, also,-` to in-r dicate yto va purchaser Whether Vthe exact amount purchased Vvvill be lsupplied'thru 'fthe delivery hose. VThe 'invention contemplates, moreover, the provision of afsectionthru which the gasoline passes .whichyvill admit of viewing the same, 'so that a purchaser may not only be enabled torchecl; up the'color'pf the liquid, Where colored varieties. aredisl pensed; but, also Will be enabled tosatisfy himself that the liquid is-in motion.' A. further object of the invention consists in thus equppnedisrensine apparatus 1.1i .sich avmanner as to permit operation thereof without affecting theregistering device for metering the total quantity siipplied thru` the pump, thereby retainingY accuracy. ofv the meter readings.; l l yTothis end, the invention 'consists inkbypassing the f pump With 1 supplementary pumping vmechanism which maybe operated When necessary to replenish, an auxiliary reservoir, the latter supplying, automatically as required, the gasoline or oil to the dispensing 'which a. level o faid chamber i l e gasoline is to vbe automatically maintained .thru the aforesaidauxiliary supply; also, in
